web.config 文件中的命名空间不起作用
我是尝试在 web.config 文件中添加命名空间，以便我可以在所有网页中使用它（在代码后面中）。但它不起作用。
有人试过吗？我之前曾问过这个，但没有得到任何合适的答案。
为了更好地理解这里是代码隐藏文件
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace TestWeb
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Label1.BackColor = Color.Red;// It is not working.
}
}
}
这是web.config文件
<?xml version="1.0"?>
<configuration>
<system.web>
<pages>
<namespaces>
<clear/>
<add namespace="System.Drawing" />
</namespaces>
</pages>
</system.web>
</configuration>
编辑
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TestWeb._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

}
</script>

</div>
</form>
</body>

How to add namespaces in web.config file?
I am trying to add namespace in web.config file, so that I can use it in all web pages (in code behind). But it is not working.
Has anybody tried it ? I have asked this before but not get any suitable answer.
To better understand here is code behind file
using System;
using System.Collections.Generic;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace TestWeb
{
public partial class _Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
Label1.BackColor = Color.Red;// It is not working.
}
}
}
This is web.config file
<?xml version="1.0"?>
<configuration>
<system.web>
<pages>
<namespaces>
<clear/>
<add namespace="System.Drawing" />
</namespaces>
</pages>
</system.web>
</configuration>
Edit
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="TestWeb._Default" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

}

<form id="form1" runat="server">
<div>
<asp:label ID="Label1" runat="server" text="Label"></asp:label>
</div>
</form>
</body>
</html>

与 VB.Net 不同，C# 没有在普通代码文件中自动包含命名空间的机制。
The
<namespaces>element only applies to aspx pages.Unlike VB.Net, C# has no mechanism to automatically include namespaces in ordinary code files.
你应该尝试这个然后再尝试。
You should try this and then try.
命名空间配置部分适用于页面，而不是代码隐藏。文件背后的代码表示其自身内的所有命名空间导入。配置中包含的命名空间将包含在从 .aspx 页面生成的动态类中。
The namespaces configuration section is for pages, not code behind. A code behind file express all namespace imports within itself. The namespaces included in configuration will be included in the dynamic class that is generated from your .aspx page.
正如 SLAks 所说，这是行不通的。如果您正在寻找一种始终包含命名空间的快捷方式，请考虑编辑默认的 VS 模板，以便在创建新模板时它始终存在。
As SLaks says, that will not work. If you're looking for a shortcut to always having a namespace included, consider editing the default VS templates, so that it's always there when you create a new one.
